IPC: G06F11/22
Filed: 1989-07-22
Abstract: PURPOSE:To prevent required data lost and to improve the workability of inspective repair by selecting whether or not the initialization of a nonvolatile memory should be performed after performing the self-diagnosis of a electronic equipment. CONSTITUTION:An initialization selecting switch 25 is provided on the upper face of a rectangular paralleopiped self-diagnostic device 21 formed in cartridge shape, and a connector part 26 is provided at one terminal of the switch. Also, three modes can be selected with the initialization selecting switch 25; a mode 1 is the one which always initializes the nonvolatile memory 14 after performing the self-diagnosis, and a mode 2 is the one which performs only the self- diagnosis and no initialization of the nonvolatile memory 14, and a mode 3 is the one which performs the initialization of the nonvolatile memory 14 only when the result of the self-diagnosis shows a prescribed state. Thus, it is possible to select whether or not the nonvolatile memory should be initialized after the self-diagnosis of the electronic equipment with an initialization selecting means. Thereby, the required data can be prevented lost, or wasteful initializing work can be suppressed increasing.

Abstract: PURPOSE:To obtain sufficient reverberation effect not only for video images but also for sound by holding the sound of the end part of a previous scene in a sound memory and superimposing it on the sound of the next scene at the time of switching screens. CONSTITUTION:A sound A of a prescribed length of the previous scene is read from the sound memory 42, specially reproduced through a special reproduction part 43 and then, superimposed on the sound B of the next scene from a VTR 2 for reproduction while performing gain control in a gain control part 46. As the contents of the special reproduction, for instance, the reverberation effect for repeatedly reproducing the sound of the prescribed length near a final scene is applied. Or, when the zero-cross point of the sound (a point where the sound ceases) is detected and the section of the zero-cross point is repeatedly reproduced, since repetition is performed at the segmenting point and the reproduction is performed, natural feeling is attained.

Title: Recording and reproducing magnetic head unified with erasion head
Inventor: GOTO NORIO
IPC: G11B5/265
Filed: 1985-08-30
Abstract: PURPOSE:To unify two magnetic heads into one body with high accuracy and to attain the accurate matching in track, by controlling the length of a magnetic gap by the width of a magnetic film formed on the surface of the 2nd block at an abutting area of the film. CONSTITUTION:The each track width Tw prescribed by a magnetic gap formed by the contact areas 14 and 15 is set by putting together both magnetic films 6 and 7 at the side of the 2nd block 2 with the widths of the films 6 and 7 set smaller than both magnetic films 8 and 9 at the side of the 3rd block 3. Thus the width Tw is constant despite some shift produced among the 1st-3rd blocks 1-3 when they are put together. In other words, the width of both films 6 and 7 are reduced to decide each track width. Furthermore, both films 6 and 7 never have a shift between them when they are put together since they are set on the same substrate. Accordingly, the track positioning at high accuracy is attained.

Title: Air conditioner
Inventor: SUZUKI TOMOKO
IPC: F24F13/14
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To suppress uncomfortableness at the time of cooling and to ensure effective warming while increasing the air flow rate by providing a sub-deflector vane having a concave face being directed reversely to the concave face of a main deflector vane when the main deflector vane is turned by a second specified rotational angle or more from a stop position for closing a blow-out port. SOLUTION: Both main flap 4 and sub-flap 5 are provided with a concave face directing the inside of a wind path. The concave face of the main flap 4 directs upward or outward of a blow-out port 3 from a position shown by a dot line during operation. At the time of a driving angle (first specified rotational angle) from a stop position, the concave face of the sub-flap 5 directs upward of the wind path. At the time of an angle (second specified rotational angle) of the main flap 4, the concave face of the sub-flap 5 directs downward of the wind path. In other words, the concave face of the sub-flap 5 directs directs reversely to that of the main flap 4. Since the sub-flap 5 has a smooth arcuate concave face directing downward, the flap substantially causes no pressure loss of blow-out.

Title: Thin film type optical element and its manufacture
Inventor: MIYAWAKI MAMORU
IPC: G02F1/11
Filed: 1985-08-29
Abstract: PURPOSE:To increase the coupling efficiency at the time of the input and output of guided light by diffusing metal into the surface of a substrate thermally and further injecting or diffusing thermally ions into the same surface, and thus forming an optical waveguide. CONSTITUTION:Parallel light 8 from a laser is converged on an optical waveguide end surface 3 by a cylindrical lens 5 in the thickness direction of the optical waveguide 2 and coupled with the optical waveguide 2. This coupled light 9 is diffracted with a surface acoustic wave 10 and the diffracted light is projected from an optical waveguide end surface 4 to become parallel light. At this time, the width of the luminous flux converged by the lens 5 on the end surface 3 is nearly equal to the width of the light 9 and the input/output light and light 9 are very close in electric field intensity distribution nearby the end surfaces 3 and 4, thereby obtaining high coupling efficiency. Further, the depth of protons injected into the waveguide 2 decreases gradually as the travels from the photocoupling part nearby the end surfaces 3 and 4 to a light function part where a surface wave 10 and the light 9 operate on each other, and the density of titanium increases, so the light is confined nearby the surface of the substrate 1 at the light function part and high diffraction efficiency is obtained.
